Jeff Falkenstine (left), an Atargis Energy Corporation mechanic, and Stefan Siegel, president and chief technology officer of Atargis Energy Corporation, demonstrate a 1:10 scale model of a cycloidal wave energy converter that the company is testing in the wave basin at Texas A&M Offshore Technology Research Center in July 2012, in College Station. Hydrofoil blades on the underwater device rotate to extract energy from waves. less

Workers ride a boat near an offshore electricity generator based on wave power off of Portugalís Atlantic coast near the northern town of Povoa de Varzim in September 2008. Portugal inaugurated a wave energy farm that uses floating tubes whose bobbing motion pumps hydraulic fluid to drive generators. less

In this undated photo provided by Finavera Renewables, a wave energy converter called an AquaBuOY is shown. Finavera's 35-ton buoys rise above the water about 6 feet but extend beneath the surface some 60 feet, where a piston encased in an underwater steel cylinder rises and falls with the waves and pushes pressurized seawater through rubber hoses. The water is then pumped into a turbine inside the buoy which spins to create power. Finavera's first ocean test last year ended in disaster when its $2 million buoy deployed off Oregon's coast sunk to the sea floor. less
